PATENT or'ricu CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OFDELAWARE JOURNAL BOX AND SIDE-FRAME SUPPORT Application riled March 21,1928. Serial No. 263,300.

This invention'relates 'to' journal boxes and side frame supports andcomprises all the features of novelty herein disclosed. An

object of the invention is to provide improved devices for yieldinglysupporting a side frame on an axle box. Another object is to provide animproved saddle for allowing a journal box to freely adjust itself withrespect to a frame to avoid cramping of the axle bearings. To theseendsaan'd to 'im rove generally and in detail upon devices 0 thischaracter, the invention also consists in the various mattershereinafter described and claimed.

The invention, in its broader aspects, is not held by a split ring 10.Roller bearings 12 having end rings 14 are interposed between thesleeve8 and a lining 16 which is inserted in the bore of an axle box or-casing17. An

end cap 18 is bolted to thebox and has a. lug

20 entering a slot 22 in a retainment ring to hold the ring fromturning. The retainment ring has a square opening to receive a squarethrust block 28 and spacing plates 28 which are clamped to the end capby a threaded stud 30 and nuts 32. The thrust block is of brass and iscast around square collars 34 of the stud 30 to hold the studfromturning. Lubricant'is admitted through a boss 38 of the end cap to areservoir. 40 in the box fromwhich point the lubricantis lifted by awick 42 'to the thrustfaces afforded by the end face of the axle and theadjacent face of the thrust block. The wick extends throughaboss 44 ofthe retainment ring and enters a notch in the thrust block where it rubsagainst the axle to deliver oil thereto. Theoll collects on a rib 46 ofthe axle and is thrown oil" into an annular groove 48 of the retainmentring, the oil then draining through a notch 50 to the bearings. A.flange 52 on the retaininent ring has grease grooves making a closejoint with the box so that the oil is compelled to traverse the bearingsbefore returning to the reservoir through a recess 54 and inclined drainpassage or core 56. The box has a flange with grease gi'ooves making aclose joint with the axle 4. Oil that may creep along the axle towardsthe flange is arrested by a rib 62 on the axle and thrown into therecess 5%.

The top of the box is provided with a pair of spaced cross lugs orguiding ledges having their inner faces Z2 slightly crowned Landreceiving loosely between them flat side flanges 7 1- on a rockingsaddle or casting 76. The saddle or casting is braced by webs 78 and 80and arches over the central portion of the axle box as indicated at 82.The saddle has a pair of rectangular recesses 84 on its under face toreceive that seat plates or blocks 86 which rest on the crowned orarched upper faces 88 of seat plates or-blocks 90 which are .set intorecesses in the top of the axle box.

The lates or blocks support the saddle and box or relative rockingmovement to prevent cramping of the bearings, the crowned face of eachplate or block 90 having a center of curvature at some point22 which isnear the lower ends of thevertical side plates 94 of the saddle and nearwhere the load is applied. The vertical side plates embrace the axle'boxwith a slight clearance to allow the saddle and box tohave a smallamount of relative rocking or twisting around a verticrowned faces 72 ofthe cross In S 70.

The side plates 94 of the sa dle have into rail horizontal seat portions96 with indined-bracing webs 98 merging with the rims 1000f the seats.Openings 102 in the seats serve to drain out foreign matterand definenel form and each comprising a web or body 114 and side legs 116 whichloosely embrace and form guiding ways for one of the pedestals 108.

I claim:

1. In a device of the character described, anaxle box, a saddle seatedonthe box for rockin movement longitudinally of the box, the sa dle andbox having relatively crowned surfaces to provide for relativetransverse twisting, the saddle having side plates embracing the boxwith a clearance to allow said relative twisting, a side frame havingpedestals closely embracing the side plates, the side plates havingparallel vertical guide flanges embracing the pedestals and forming waysto guide the pedestals vertically, and springs inter osed between theends of the pedestals an the lower ends of the side plates;substantially as described.

2. In a device of the character described, an axle box having cross lugson its upper surface, a saddle seated on the box between the cross lugs,the sides of the saddle and the cross lugs having relatively crownedsurfaces extending transversely of the box to provide for relativetwistin of the box and saddle, the saddle having side plates embracingthe box with a clearance to allow said twisting, and a side framesupported by the side plates substantially as described.

3. In a device of the character described, an axle box having cross lugswith inner crowned surfaces, a saddle seated on the box and having sidefaces to engage and rock with respect to the crowned surfaces, thesaddle having side plates embracin the box, and a side frame supportedby t substantially as described.

4'. In a device of the character described, an axle box, a saddleextending over the box and having side plates embracing the box, the topof the box having spaced crowned surfaces near the sides and the bottomof the saddle havin flat surfaces su portedon the crowned sur aces;substantial y as described.

5.- In a device of the character described, an axle box, a saddleextending over the box and having side lates embracing the box, the topof the box avin spaced recesses near the sides, supporting locks in therecesses, the bottom of the saddle having spaced recesses,

and supporting blocks in the recesses and seated on the first mentionedblocks; substantially as described. a

- 6. In a device of the character described an axle box, a saddleextending over the ox and having side plates embracing the box,

ing the saddle; substantially as described.

In a device of the character described anaxle box, a saddle extendingover the ox and having sideplates embracing the box,

e side plates;

the box and the saddle having relatively crowned supporting surfaces toallow rocking movement longitudinally of the box, the box and the saddlealso having relatively crowned guide surfaces extending crosswise of thebox; substantially as described.

8. In a device of the character described, an axle box, a saddle seatedon the box and havin side plates embracing the sides of the box with aclearance to allow twisting of the box transversely, the side plateshaving seats for springs and parallel guiding ways for pedestals, a sideframe having pedestals fitting in the guiding ways to maintain thesaddle and side frame in substantial alignment, and springs between theends of the pedestals and the spring seats of the saddle; substantiallyas described;

In testimony whereof I hereunto aflix my signature.
